Transaction processing systems (TPS) are used to record daily business transactions in a database and provide immediate responses. Examples include systems for banks, billing, payroll, and reservations. Office automation systems (OAS) create, store, and share office documents and information to accomplish tasks without manual work. Knowledge work systems (KWS) capture and develop organizational knowledge at workstations. Decision support systems (DSS) help users analyze information and make decisions by combining computer and human inputs. Executive support systems (ESS) transform enterprise data into quick executive-level reports. Group decision support systems (GDSS) provide digital tools to support customized group projects and inputs.
